3. BetaProbe TI High Accuracy Digital Thermometer User Reference Manual MARTEL LECTRONICS 1 Introduction The BetaProbe Tl is designed to be a high precision digital thermometer that can be used in place of mercury liquid in glass LIG thermometers It can also be used as a reference standard to check the accuracy of other types of digital or analog thermometers Because of its intrinsically safe certification it can be used in many of the same hazardous locations as analog thermometers The long stem 3 16 diameter probe houses a fast responding thin film sensor that allows very accurate readings to be taken quickly and with minimal insertion depth A rotatable probe mount allows for both horizontal and vertical orientation of the display module A unique feature of the BetaProbe TI are the trend indication arrows which the user can configure to show when the readings are considered to be stable enough to record the reading Additional features such as min max storage selectable sample rate auto shutoff backlight and damping allow the user to tailor the TI for their Specific application Battery life is up to 300 hours With the auto shutoff feature the typical user may only have to change the batteries a few times per year 1 1 Customer Service Corporate Office www martelcalibrators com e mail sales martelcorp com Tel 603 434 1433 800 821 0023 Fax 603 434 1653 Martel Electronics 3 Corporate Park
